Feature request: Tooltip on hover

[daniel-sc]

Currently the tooltip can only be triggered on click - we'd need the tooltip to trigger on hover of an arbitray elements. There should be configurable delays for show/hide.

Additional context
As an orientation one could check: https://ng-bootstrap.github.io/#/components/popover/examples

To give you some context, this is one of our use cases:
We have a data heavy table that our users need to skim fast and regularly need a subset of details to understand the context. Because this is a repetitive task, we need to prevent a back-and-forth between the master and detail views and we use progressive disclosure to do that:

The delay is necessary to allow the users to move their mouse cursor over the table, without annoying tooltips flipping up during the movement.
